Have you checked that GCC doesn't already optimize the functions here
into these instructions? If it doesn't, maybe we could write them in a
way that GCC more easily recognizes.
But if that's not the case, I don't see any particular reason we
couldn't do this.

Hi,
I am proposing the following changes to mono-endian.h to optimize
little-endian to big-endian processing for s390x. The architecture defines
instructions for just this purpose so instead of doing shifts etc. we can
just do this:
--- a/mono/metadata/mono-endian.h
+++ b/mono/metadata/mono-endia
